BioLogic DuoFlow Maximizer 80 System

Overview

The BioFrac fraction collector can be used for basic or complex fraction collection schemes at flow rates <100 mL/min. Available stand-alone or with the BioLogic DuoFlow and LP systems, this fraction collector offers flexibility with numerous collection rack options ranging from an icebath/microplate rack to a prep-20 preparative scale rack for large volume collection. Collection in time, drop, or volume mode with peak detection, time windows, or a combination of both.

This pH monitor enables real-time monitoring of pH conditions (pH 1–14) during a sample run. It consists of high-precision calomel electrodes which are compatible with buffers such as Tris that are incompatible with Ag/AgCl electrodes. It is a biocompatible PEEK flow cell with a swept volume of approx 80 µL that is capable of withstanding flow rates to 80 mL/min. The monitor is included with all BioLogic Maximizer™ and Pathfinder® systems and is available as an option on the BioLogic DuoFlow™ and BioLogic DuoFlow QuadTec™ systems, where it connects via the Signal Import Module (SIM).

This optional module allows import of an analog signal (up to 2.5V) from a pH electrode or other external detector (such as a UV, refractive index, or fluorescence monitor). The BioLogic DuoFlow software accommodates two SIMs and can display four data signals simultaneously.

High- and low-pressure valves are available. High-pressure sample injection (AVR7-3) and stream select (AVR9-8) valves use the patented MBB (make-before-break) design that prevents pressure spikes when the valve rotates from one port to another, eliminating baseline interference. The feature is beneficial when using fragile low-pressure columns or flow-sensitive detectors and prevents pump shutdown due to transient pressure conditions.

The BioLogic DuoFlow family of chromatography systems offers flexibility with multiple system configurations, many optional upgrades, and a common software platform that is intuitive and easy to follow. These systems can be used on the laboratory bench or in a coldroom.
